This product has the same review as another product and it doesn’t work. I would like my MONEY back.
Just didn’t do what they said it would do. What a complete waste of money.

Works only if you have the right code reader
The connector works fine and allowed me to connect my auto code reader to my Freightliner rv. The problem for me is that my “car” reader could not read the codes from my rv.
